Empty tile skipping in grid slice not compatible with most Tilemappers

I just wasted 2 hours, thinking my tilemapper had a bug, so maybe I can save you some time.

This is also a form of feedback, as this feature currently renders many popular tilemappers useless if you use spritesheets. A toggle button would be greatly appreciated

In grid slice mode, unity is skipping all tiles that are empty / contain no pixels

This means that the order / index of ALL following tiles shifts by -1 for each empty tile in the spritesheet

The linked image clearly shows the issue. There's an empty tile, meaning unity skips it and all other tiles shift by -1. The used tilemapper behaves as expected and still counts empty tiles. This introduces completely unnecessary work, as you now have to make sure no spritesheet contains empty / completely transparent tiles

 

I agree, this is a bit of a pain. Any solutions?

I nominate this entry into the worlds biggest hack contest. If you are TRULY desperate this works.

Generate your tiles normally. Select this script, drop your tileset in and hit Split Tiles.

Viola, proper tiles.


[Warning] The degree of this hack is equal to US national debt.


Any real solutions would be nice.

Hey, I haven't experienced this kind of issue. I use the Sprite Editor to cut the tiles I need and then create tile prefabs and tile them myself, with a TileMap script.

But I experience a totally different issue, where Unity's camera is not pixel perfect and if he camera moves you can see pixel distortions on the tiles (pixels shifting left and right). Any more input would be appreciated. I've posted a temporary fix in one thread.

 

I dont want to mix this thread up with other issues as they tend to get off topic and lose the original point. I have heard of that error a few times. I personally fixed it by setting the filter mode on the tileset to point. Either way there should be plenty of info around to fix it.

 

I found a workaround for this problem. You can fill spritesheet background with some color and slice it. Then you need to replace your original spritesheet via explorer (in Windows).

I am facing the same problem, I spent 10 votes on this. This should be on Unity long ago.

 

My personal solution has been to put some pixels with an alpha value of 1 in the slices that are supposed to be empty. Shouldn't be noticeable in most cases and it prevents Unity from ignoring them.

 

super frustrating this is not an option still?
Here i scribble tmeporary pixels to make sure my future mappings arent corrupted when we add to the tilesheet.

SIMPLE: Ignore White Space?

 

I totally agree with this. There should be option to keep the empty sprites.
